SteamWeasel

If you're looking for a multiplayer game that can handle simultaneously executed turns, you should try SteamWeasel. This game has a central server that manages the turns in real-time. To ensure seamless communication with the server, emails are used instead of dealing with firewalls, which can be quite bothersome.

One of the significant features of SteamWeasel is its extensible engine that can handle both "content" and "helper" bundles. With SteamWeasel, you can add various plugins to improve your gaming experience, making it more dynamic.

SteamWeasel prides itself on its radically open architecture, implying that it won't do much without any installed plug-ins. Therefore, feel free to customize your game and add as many plugins as you desire to enjoy the full potential of SteamWeasel.

Note that SteamWeasel is licensed and released under the BSD License, offering users the freedom to use and modify the game's code as per their needs. So, if you're a gaming enthusiast and love to experiment with games, go ahead and try SteamWeasel to experience the excitement of multiplayer gaming.
